Labor productivity in the United States and the United Kingdom during the nineteenth century

A number of writers have recently questioned whether labor productivity or per capita incomes were ever higher in the United Kingdom than in the United States. This paper focuses on aggregate and sectoral labor productivity in the two countries during the nineteenth century. We build on earlier work by Broadberry to push comparative productivity estimates back to 1840 based on a time series projection from a 1910 benchmark and checked against a benchmark estimate for 1850. The results indicate that labor productivity in agriculture was broadly equal in the two countries, and that the United States had a substantial labor productivity lead in industry as early as 1840, while the United Kingdom was ahead in services. Hence aggregate labor productivity and per capita incomes were higher in the United Kingdom in the mid-nineteenth century, particularly since the United States had a larger share of the labor force in low value-added agriculture and a smaller share of the population in the labor force.
